Complaints Management System / Trouble Ticket System Design

Hi Folks,
We are going to develop a trouble ticket system.
Currently we are about to start design phase and requirements are almost complete.

Here in this question i would like to seek help regarding WorkFlow. How can we design and implement the workflow of ticket, by workflow i mean the different stages/departments a ticket/complaint will go. whats the best way to design this so that we can later be able to add a new stage/department in between the existing steps/workflow.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Two thing come immediately to mind:

(1) UML Activity diagrams ( and  They are specifically for the purpose you need.

(2) UML State diagrams ( and  These diagrams help capture and organize the different "stages" (states) and how they go between them (transition).

These two UML diagrams will help you create and maintain your work flow.

Hi khalidmehmoodawan,

While I agree with what Mark says, there are other diagram types that will do the same as activity diagrams. These are
Petrinets and BPNM.

Tools and Info:

As the wikipedia article also states there are also Business Process Modeling Notation (BPMN)
